Grocery's future is online, Relay CEO says

Relay Foods CEO Zach Buckner predicts that within a few years, more people will buy groceries online than in a traditional store. "I think the grocery store will be similar to the bookstore or the video store 10 years from now," Buckner said. "The future took a long time to happen, but we are now at the point where the future is happening all at once." Virginia-based Relay offers home delivery or pickup.
